高级氧化法处理电子工业TMAH废水研究进展
Advances in advanced oxidation technology for the treatment of TMAH wastewater in electronics industry
对多种方法处理电子工业TMAH废水进行了综述,包括Fenton法、光催化技术、臭氧氧化法、UV/H2O2工艺以及过硫酸盐活化工艺等。结合活性自由基特征反应机制,TMAH的降解路径被阐明为以逐步去甲基化为主并最终生成NH4+和NO3-。
A review of various methods for treating TMAH wastewater from the electronics industry is presented,including the Fenton method,photocatalytic technology,ozone oxidation,UV/H2O2 processes,and persulfate activation processes et al.Based on the characteristic reaction mechanisms of active radicals,the degradation pathway of TMAH is elucidated as primarily involving stepwise demethylation,ultimately yielding NH4+ and NO3-.
